He realized that living cells produce new cells through division. While looking at cork, Hooke observed box-shaped structures, which he called cells as they reminded him of the cells, or rooms, in monasteries. co-discoverer of superfluidity Altman, Sidney: 1989 Nobel Prize winner in chemistry. Their theory accepted the first two tenets of modern cell theory (see next section, below). The classical cell theory was proposed by Theodor Schwann in 1839.

First proposed by German scientists Theodor Schwann and Matthias Jakob Schleiden in 1838, the theory that all plants and animals are made up of cells marked a great conceptual advance in biology and resulted in renewed attention to the living processes that go on in cells. Although cells are diverse, all cells have certain parts in common. It is, however, easy to perceive that the vital process of the individual cells must form the first, absolutely indispensable fundamental basis, both as regards vegetablephysiologyand comparative physiology in general. Luckily, we have Robert Hooke, a 17th-century English scientist to thank; he discovered that cells exist in the first place. 1 Who were the 5 scientists who contributed to the cell theory?

Hooke's discovery help paved the way to the rejection of spontaneous rejection by demolishing the idea that living things came out of nothing or nonliving things. Three critical discoveries made during the 1830s, when improved microscopes with suitable lenses, higher powers of magnification withoutaberration, and more satisfactory illumination became available, were decisive events in the early development of cell theory. Somewhat amazingly, his great discovery came as a result of dinner with Schleiden. Cell Theory Timeline | Biology Dictionary What are the three scientists contributed to the cell theory?
